What are they going to do about all the other uses of the word nexus for businesses, publications, websites, et bleeming cetera?
Meaningless. As JAR pointed out, it's a trademark issue, nothing to do with copyright. Trademarks protect the specific use of a name or phrase (and possibly certain graphic representations of that name) connected with a specific product or service. And, unlike copyrights, which are automatic with the tangible creation of specific verbal text, trademarks
must be registered on a formal basis. A good example would be the former World Wrestling Federation, or WWF, which was forced to change its name to World Wrestling Entertainment (WWE), on the basis of a trademark challenge from the World Wildlife Fund, which had trademark protection on the WWF designation.
Unless the PKD heirs have formal trademark protection on their Nexus phone idea, I can't imagine this litigation getting any traction. And Google, with all its billions of dollars, is not very likely to settle something this frivolous out-of-court. They'll squash this action the way you'd swat a mosquito.
